  • Title: Transvenous embolization of dural caroticocavernous fistulae: technical considerations.
    Author: Yamashita K, Taki W, Nishi S, Sadato A, Nakahara I, Kikuchi H, Yonekawa Y.
    Journal: Neuroradiology; 1993; 35(6):475-9. PubMed ID: 8377926.
    Abstract:
    Sixteen patients with symptomatic dural caroticocavernous fistulae were treated by transvenous embolization, via the jugular vein and inferior petrosal sinus. The fistula was occluded by thrombogenic coils. Complete resolution of symptoms and signs was achieved in 14 patients, and complete angiographic resolution was also obtained in 14 patients. Failures to achieve angiographic cure were attributed to failure to reach the fistula within the cavernous sinus precisely. Factors which make placement of the catheter at the fistula difficult are trabeculae within the cavernous sinus, a specific configuration of the superior ophthalmic vein and venous thrombosis. To improve the efficacy of transvenous embolization, every possible venous route to the cavernous sinus therefore should be tried, to facilitate reaching the fistula and the possibility of transvenous embolization should not be thwarted by venous thrombosis.
